Q:After I create and enter the portal, I can see an unknown user in the People module with the 'fake user' name. There is also some OnlyofficeHealthCheck service in the services list. Why is this and do I need to do something about it?

A:The user and the service are a part of the upcoming Health Check functionality which will be available for the portals in the future releases. As for now it is not functional, so you can either leave it as is or disable the OnlyofficeHealthCheck service and remove it from the service automatic startup list.

Q:What system do I need to have to install the server solution and successfully use it?

A:The system requirements are:

CPU

dual core 2 GHz or better

RAM

2 GB or more

HDD

at least 2 GB of free space

Additional Requirements

at least 2 GB of swap

OS

amd64 Linux distribution with kernel version 3.10 or later

Additional Requirements

Docker: version 1.10 or later

Q:I installed one of the servers using Docker service, but it lacks performance. I am sure that my computer meets all the requirements. What can be wrong?

A:Docker specifies Google DNS servers by default and the server tries to contact them every time it makes some network requests. It stalls the performance due to the DNS server inaccessibility if no Internet connection is present. So if your Community Server, Document Server or Mail Server is not going to have access to the Internet, we recommend that you change the default Docker DNS address to the address of your local DNS server. To do that go to the /etc/default/docker file and change the IP address in the following line to the IP address of a DNS server in your local network:

docker_OPTS="--dns 8.8.8.8"

Q:The document editors open and the interface appears, but the document itself does not load, continually showing loading progress. What can be done?

A:The reason might be that the computer must be able to address itself using the Internet loopback access, i.e. it must be accessible from outside for itself. You can allow it to do that editing the iptables to have the redirects like this:

Do not forget to substitute the public_ip and the local_ip addresses with the real IP addresses.

Q:I updated my editor language files (corrected some translations) but the server still shows the previous values instead of the correct ones. How can I reset the cache for all the users at the same time?

A:Please follow the steps to reset the cache:
Find the /etc/nginx/includes/onlyoffice-documentserver-docservice.conf and /etc/nginx/includes/onlyoffice-documentserver-spellchecker.conf files. There must be the build date and time value. Change these values to some other (any value will do, but the main thing that it must be the same in all the places), and restart NGINX:

sudo service nginx reload

The cache should be reset for all the server users.

Please note that for the Docker installation all the actions must be performed within the container.

Docker issues

Q:I rebooted the server without stopping the docker container with docker stop id command and now I have the ERR_TOO_MANY_REDIRECTS error for my server. What can be done to fix that?

A:Please edit the /var/www/onlyoffice/WebStudio/web.appsettings.config file removing the very last line:

<add key="web.warmup.type" value="basic" />

and restart monoserve with the following command:

sudo service monoserve restart

Q:I'm using Fedora Linux and processes fail to start inside Docker container. Is there a fix to the issue?

A:Fedora and RHEL/CentOS users should try disabling SELinux with setenforce 0 command. If it fixes the issue then you can either stick with SELinux disabled which is not recommended by RedHat, or switch to using Ubuntu.

Document Server usage issues

Q:Data loss has occured when stopping Document Server. How to prevent data loss?

A:Due to the operational characteristic, Document Server saves a document only after the document has been closed by all the users who edited it. To avoid data loss, you must forcefully disconnect the Document Server users when you need to stop Document Server in cases of the application update, server reboot etc. To do that, execute the following script on the server where Document Server is installed:

sudo docker exec <CONTAINER> documentserver-prepare4shutdown.sh

Executing the script may take a long time (up to 5 minutes).

Disconnecting users may take a long time (up to 5 minutes).
